Recommended Dietary Allowances
An Iodine intake of 150 mcg/day has been suggested as sufficient for all adults and adolescents.
The RDA for pregnant and lactating women is increased to 25 mcg and 50 mcg respectively.
The RDA is 40 mcg for infants up to 6 months of age, and 50 mcg for older infants.
The RDA for children is between 70 and 120 mcg, increasing with age (or body size).

Biochemical and Metabolic Functions of Iodine.....
Iodine is a trace element essential for the metabolism of fat and minerals. It is important for physical and mental development. Iodine is concentrated in the thyroid gland and is an essential component of the thyroid hormone, thyroxine, which is the master regulator of metabolism.
Iodine increases metabolism, ie pulse rate, respiration, arterial pressure, quality of urine.
The primary role of iodine is for the synthesis of thyroid hormone thyroxine(T4) and triiodothyronine(T3) by the thyroid gland.

Iodine Deficiency-Part 3
Besides goiter, iodine deficiency can also cause cretinism - a preventable mental retardation. Cretinism is a condition of severely stunted physical and mental growth due to untreated congenital deficiency of thyroid hormones or congenital hypothyroidism, due to iodine deficiency affected pregnancy.
The infants with cretinism usually have poor length growth at the first year of life. In addition, they also have delayed bone maturation and puberty. Infertility in both sexes is common as well. They may also have mild neurological impairment along with reduced muscle tone and coordination.
In severe cases, they cannot walk or stand by themselves. Cognitive impairment may occur in different severity that they may not able to take care of themselves. They thoughts and reflexes are tend to be slower.
In conclusion, sufficient iodine intake is especially important in women who are pregnant or nursing their infants. Severe iodine deficiency in the mother can cause miscarriages, stillbirth, preterm delivery, and congenital abnormalities in their babies. There are studies suggested that even mild iodine deficiency in the mother can result lower intelligence children.

Iodine Deficiency - Part 1
According to American Thyroid Association(ATA), iodine is an element that is needed for the production of thyroid hormone. Our body does not make iodine, so it is an essential mineral and only come from our diet.
Iodine not only found in iodized salt, it also can be found in breads, cheese, saltwater fish, cow’s milk, seaweed (including kelp, dulce, nori), eggs, shellfish, frozen yogurt, soy milk and soy sauce. We need enough iodine in our body to make enough thyroid hormone.
Iodine deficiency can lead to enlargement of the thyroid—goiter, hypothyroidism and mental retardation in infants and children whose mothers were iodine deficient during pregnancy.
* I am going to explain how iodine is related to goiter in next post. Thanks for stopping by.
